Key Features

80kW Three-Phase Hybrid Power

The inverter delivers up to 80kW of rated AC output power, making it suitable for high-demand commercial and larger-scale energy storage installations. Its three-phase configuration provides balanced and reliable power distribution while supporting applications with varying phase loads.

High-Voltage Battery Compatibility

The SUN-80K-SG02HP3-EU-EM6 is designed to work with high-voltage lithium-ion battery systems from 160V to 1000V.

The high-voltage architecture helps support efficient energy transfer between the inverter and battery bank while providing flexibility when designing larger battery storage systems.

High Battery Charging and Discharging Capability

The inverter supports a maximum charging/discharging current of up to 160A (80A + 80A), allowing substantial battery power to be transferred during charging and discharging cycles.

This makes it suitable for applications requiring rapid energy storage during periods of solar production and high-power battery discharge during peak demand or grid outages.

AC Coupling for Existing Solar Systems

The AC-coupling capability allows the inverter to be integrated into existing solar installations.

This makes the SUN-80K-SG02HP3-EU-EM6 an excellent option for solar system upgrades and battery-storage retrofits, allowing existing PV systems to be enhanced with additional energy storage without necessarily replacing the complete installation.

Diesel Generator Compatibility

For installations requiring additional backup power, the inverter supports diesel generator integration.

A generator can be incorporated into the energy system to provide additional power during extended grid outages, periods of insufficient solar generation, or when battery capacity is low.

On-Grid and Off-Grid Operation

The Deye 80kW hybrid inverter can be configured for both grid-connected and off-grid applications.

This enables it to support a wide range of energy strategies, including:

• Solar self-consumption
• Battery energy storage
• Peak-load management
• Backup power
• Grid-tied operation
• Off-grid operation
• Generator-assisted operation
• Solar-plus-storage systems

Parallel Operation – Up to 10 Inverters

Up to 10 units can be connected in parallel, allowing the overall system capacity to be expanded as energy requirements increase.

Parallel operation makes the inverter suitable for larger commercial and industrial energy storage systems where a single 80kW inverter may not provide sufficient capacity.

100% Unbalanced Load Support

The inverter supports 100% unbalanced output per phase, making it suitable for three-phase installations where electrical loads are not evenly distributed between phases.

This feature provides greater flexibility when supplying buildings with a combination of single-phase and three-phase loads.

1.5× Peak Power Capability

The inverter can provide up to 1.5 times its rated power for 10 seconds.

This temporary peak-power capability helps the system accommodate demanding loads and equipment with higher starting or surge requirements.

Six Programmable Time Periods

The inverter provides six configurable time periods for battery charging and discharging.

This allows installers and system owners to create customised energy-management schedules based on electricity tariffs, solar production, battery availability, and site energy requirements.

Possible applications include:

• Charging batteries during off-peak periods
• Storing excess solar energy
• Discharging batteries during peak-tariff periods
• Reducing grid consumption
• Maximising solar self-consumption
• Supporting time-of-use energy strategies

Advanced Communication and Monitoring

The SUN-80K-SG02HP3-EU-EM6 provides multiple communication interfaces for system monitoring, configuration, and integration.

Available interfaces include:

• RS485
• RS232
• CAN

Optional communication technologies may include:

• GPRS
• Wi-Fi
• Bluetooth
• 4G
• LAN

These communication options allow the inverter to be integrated into suitable monitoring and energy-management environments, depending on the selected configuration.

Advanced Protection Features

The Deye 80kW hybrid inverter incorporates multiple protection functions designed to improve system safety and operational reliability.

Depending on the system configuration, protection features include:

• Over-voltage protection
• Under-voltage protection
• Over-current protection
• Short-circuit protection
• Over-temperature protection
• Grid protection
• Battery protection
• Anti-islanding protection
• Surge protection
• Arc-fault detection, where supported/optional

These protection functions help safeguard the inverter and connected electrical equipment against abnormal operating conditions.

IP65 Outdoor-Rated Design

The inverter features an IP65-rated enclosure, providing protection against dust ingress and water exposure suitable for outdoor installation when installed according to the manufacturer’s requirements.

Its robust enclosure makes it suitable for a variety of environments, including:

• Commercial buildings
• Industrial facilities
• Warehouses
• Agricultural installations
• Solar farms
• Battery energy storage installations
• Backup power systems
